Black Hawk Mines Bulletin is all for the preservation and promotion of mining ghost towns that are widely being neglected across the world. We support historical sites and promote the rebirth of current mining ghost towns that still have a lot of potential in generating income and historical value.



This blog regularly publishes news and details regarding mining-sites-turned-ghost-towns to educate people interested in history and to gather support for our cause from different parts of the world.



Our group is presently working alongside other associations to keep ghost towns, like the BlackHawk, Colorado, in the map; perhaps, even to try and make them a tourist spot.

Two of the biggest mining firms in the world, Rio Tinto PLC and BHP Billiton Ltd are teaming up to invest over USD 4 billion to boost their copper output, according to their announcement on Tuesday.

Rio and BHP have staked their investment on a high copper demand worldwide as they approve plans for USD 4.5 billion expansion of their Escondida mine in Chile. BHP is even reopening their copper mine that has been out of commission since 2009 due to the global fiscal crisis.

The mining site that will produce molybdenum concentrate and copper is expected to have a yearly production of around 60,000 tonnes. Moreover, BHP expects that this resumption of operations will provide for 650 new jobs.

Majority of the money is set to be invested in the Escondida operation located in the southeastern part of Antofagasta, Chile. In addition to this, BHP is also planning to resume its operations at the Pinto Valley in Arizona before the year ends.

The recovery in ore grades combined with current work at Escondida should aid them in their target production of over 1.3 million metric tonnes by 2015. This is exclusive of the 60,000 tonnes of copper concentrate that the Pinto Valley is capable of producing yearly, according to BHP.

Last year, operations at Escondida was distracted by labor strikes and lower grade ores but Rio and BHP announced that output is anticipated to increase from 2013 due to the higher grade ore in the main pi...
